Time-dependent evolution of the Bi3.64Mo0.36O6.55/Bi2MoO6 heterostructure for enhanced photocatalytic activity via the interfacial hole migration

Hierarchical Bi_3.64Mo_0.36O_6.55/Bi₂MoO₆ heterostructures displayed enhanced photocatalytic activity for dye photodegradation due to efficient electron–hole separation and interfacial hole migration from inner Bi_3.64Mo_0.36O_6.55 layer to outer Bi₂MoO₆ layer.
